GrowableArrayMarker was a class that implemented int and was used to
enable implementation of default List factory constructor in pure Dart:
factory List([int length = GROWABLE_ARRAY_MARKER]) {
return identical(length, GROWABLE_ARRAY_MARKER) ? new _GrowableList<E>(0)
: new _List<E>(length);
}
Its existence complicated all kinds of things in the VM and it is finally
time to remove it.
Instead we build List factory body directly in IL.
This CL also provides inlining rule for `new List(n)` case.

Update status files.
This cl includes implementing these two features on all platforms:
1) Support calling generic functions via DartEntry::InvokeFunction().
2) Support native generic functions. These are currently allowed, but type
arguments are ignored, and therefore not accessible from the C++ side.

Now that we do eager rehashing of linked hashmaps we no longer have the
index field be `null` (which in the past signaled we needed rehashing).
This means we can teach the optimizer that loads from the index fied
always result in kTypedDataUint32ArrayCid.

CloneContext is implemented as a runtime call so it is considerably slower
than AllocateContext which leads to performance issues in loops that capture
iteration variables in for loops.
Lowering CloneContext into AllocateUninitializedContext and a sequence of
explicit load&store instructions both improves the performance by avoiding
the runtime call and also makes CloneContext semantics exposed to store-load
forwarding and allocation sinking.
PutIfAbsent benchmark from issue #31113 is improved by 5x, while
ForInGeneratedLoop benchmark is improved by 8x.

Currently, we have some tests that run with reified generic functions ON and
some with it OFF. However, this causes inconsistencies when running the Kernel
FE from snapshot in the VM, since the VM requires that the flag be consistent
with the snapshot. Our solution is to turn the reified generic functions flag
into a per-isolate flag, which is always disabled in the Kernel FE's isolate.
